INVENTOR ATTORNEYS Patented Aug. 19, 1941 UNITED STATES PATENT OFFICE 2,252,994 ,7 g RODENT AND INSECT EXTERMIINATOR Nicholas R. Tench, Peosta, Iowa Application November 20, 1939, Serial No. 305,362

1 Claim.

This invention relates to sprayers, and its general object is to provide an attachment that is designed for use with an ordinary manually operated tire pump for cooperation therewith pri-.

Cir

movable cap having inlet and outlet means for l the passage of air from the pump Within the container through the inlet means to force the contents of the container therefrom through the outlet means.

Another object is to provide an exterminator attachment that is simple in construction, inexpensive to manufacture, and extremely efficient in use and service.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the app-ended claim.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding view taken through the container and its cap,

with the inlet means in section and the outlet means in elevation.

Figure 2 is a side elevation of my attachment secured to the pump.

Figure 3 is a top plan view of the clamp for securing the attachment to the pump.

Referring to the drawing in detail, the reference numeral I indicates an ordinary manually operated tire pump that includes a cylinder secured to and rising from a foot receiving base 2, a handled rod 3 for the piston, not shown, and a hose 4 having the usual threaded outlet coupling 5 secured to the outer end thereof; all of which forms no part of the present invention that lies solely in the attachment for use with the pump.

The attachment as best shown in Figure 2, includes a container 6 which may be a glass jar of the Mason type, but in any event is provided with a threaded neck I for threadedly receiving a skirted cap 8 provided with a gasket 9 to provide a leak proof connection between the cap and jar, as will be apparent upon inspection of Figure 1.

Extending through the top of the cap and secured to and rising therefrom is a straight elongated tubular inlet nipple l0 having a threaded upper end for receiving the outlet couplings 5 of the hose 4, and the nipple I0 is fixed to the cap by nuts I l threaded on the lower end thereof and engaged with washers l2 which in turn are engaged with the upper and lower faces of the top of the cap, as clearly shown in Figure 1.

A straight elongated tubular outlet nipple I3 is likewise secured to the top of the cap by nuts [4 bearing against washers I5, and the nipple [3 extends through the top and rises therefrom, as well as is provided with a threaded upper end for receiving a coupling l6 identical to the coupling 5 and the coupling [6 has one end of an outlet hose l'i secured thereto.

The container is attached to the pump cylinder by a clamp which as best shown in Figure 3, includes a relatively large collar portion l8 for surrounding and clamping engagement with the container, and from the collar portion I8, the clamp is provided with a pair of parallel portions 19 that extend into substantially semi-circular portions 20 for disposal in clamping engagement with the cylinder. The semi-circular portions are secured accordingly by a bolt and nut connection 2! having the bolt thereof extending through ears 22 and the collar portion I8 is secured about the container by a bolt and nut connection 23 having the bolt thereof extending through the parallel portions l9. By that construction, it will be obvious that the container can be easily and expeditiously applied and removed with respect to the cylinder.

Inthe use of my attachment, it is believed that it will be obvious that the container is filled with any suitable exterminating powder, such as insecticide or the like, either before or after being attached to the pump. In any event, the hose 4 is connected to the inlet nipple I0 and upon operating the pump, it will be further obvious that air under pressure is introduced within the container for forcing its contents therefrom through the outlet nipple l3 for disposal through the outlet hose ll, which of course is used for directing the insecticide or the like, as desired, for example toward plants for killing insects thereon, or within rodent nests or holes.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

What I claim is:

A spraying attachment for an upright cylinder air pump having an outlet hose, said attachment comprising a container, a removable cap closing said container, straight elongated tubular inlet and outlet nipples having threaded upper and lower end portions, the lower end portions extending through the cap for disposal of the nipples in parallelism with each other and with the nipples rising from the cap, washers on said lower end portions and engaged with the inner and outer faces of the top of the cap, nuts threaded on said lower end portions and bearing against the washers to provide a leakproof connection between the cap and nipples, the upper end portion of the inlet nipple having the hose threaded thereon for passage of air from the pump into the container, an outlet hose for the contents of the container and threaded on the upper end of the outlet nipple, and means detachably connecting the container to the cylinder of the pump for disposal in parallelism therewith.
